PATENT OFFICE ES MOND I. WILEY, 0]! SAN FRANCISCO, CALIFORNIA, 'ASSIGNOR'IO UNIVERSAL WIN- DOW GOIPANY, OF OAKLAND, CALIFORNIA, A CORPORATION OFCALIFORNIA AWNING TYPE WINDOW OPERATOR Application filed January 29,1930. serial No. 424,222.

This invention relates to apparatus for operating awning type windows.

Hitherto, school and like buildings have been fitted with awnin typewindows unequipped with mechanism connecting the sashes together so thatthe sashes would opcrate in unison and consequently thesashes had to beoperated individually by a window pole. This, v of course, is entirelyunsatisfactory and therefore it is the principal ob ect of the presentinvention to provide a simple and inexpensive apparatus which may beaplied to awning type windows without altermg their construction andwhich enables all of the sashes to be operated by the operatlon of thelowermost sash which also may be operated independently of the others.

In carrying the invention intov practice, I connect the sashes togetherby means of an operating rod to which the lowermost sash 1s latched, sothat by operation of the lowermost sash all of the sashes may bemanipulated. By releasing this latch, however, the lower sash mayoperate independently of the other sashes.

One form which the invention may assume is exemplified in the followingdescr ptlon and illustrated by way of example in the accompanyingdrawing, in which:

Fig. 1 is a view in vertical section through an awning type windowequipped with my improved apparatus.

Fig. 2 is a fragmentary view in elevation showing the mounting of myapparatus on the window.

Fig. 3 is a view similar to Fig. 1 showing. the apparatus mounted on thewindow w1th the sashes in closed position.

Fig. 4 is a fragmentary view in plan section showing the connection'between the operating rod and the sash.

Referring more particularly to the accompanying drawing, 10 indicates awindow frame wherein three sashes 11 are mounted. This window is of theawning type and for this reason the upper ends of the sashes arepivotally and slidably connected to the frame. This connection includesshoes 12 pivoted to the sashes at the sides thereof and guided forvertical reciprocation in guide grooves 14 which are disposed betweenthe sides of the I sashes and the frame and which are pivoted at one endto the frame and at the other to the sashes. The point at which thefulcrum links connect with the sashes is intermediate the ends of thelatter so that the sashes will swing in a vertical plane as illustratedin the drawing.

The present invention, however, is particularly concerned with amechanism for operatlng the sashes. Th1s mechanism lncludes a pair ofbrackets 16 for each sash. These brackets are fixed one at each side ofthe sash at the upper end thereof and project inwardly as illustrated. Avertically reciprocable operatin rod 17 is arranged at each side of thewin ow. Connectors 18 are adjustably mounted on these rods and arepivotally connected to adjacent brackets 16 so as to operatively connectthe rod to the upper sashes. Due to these connections it is obvious thatthe upper sashes will operate in unison.

At the lower end of each rod a sliding connector 19 is provided which ispivoted to the the adjacent'bracket 16 on the lower sash. On each rod 17just below the sliding connector 19 is fixed a latch support 20 which isvertically adjustable on the rod. This latch support 20 is fitted with apivotal latch bolt 21 which is adapted to cooperate with alatch boltkeeper 22 formed on the sliding connector 19. The latch bolt ispivotally connected with the latch support 20 and is yieldablymaintained in latching position by a spring 23. The latch bolts 21 atopposite sides of the sash are connected together by a chain or cord 24so that by pulling downwardly on the cord both latch bolts 21 may bereleased simultaneously. When the latch bolts are released the lowersash is free: to swing independently of the upper sashes.

In operation of the device, assuming that the sashes are closed and thatthe latch connections between the lower sash and the rods are effective,opening movement of the lower sash will, of course, be accompanied bydownbrackets 16 the upper sashes will swing in unison with the lowersash.

As it is often desirable that the lower sash be closed while the uppersashes are open after the sashes have been opened in order to close thelower sash without effecting the position of the upper ones, it is onlynecessary to exert a pull on the cord or chain 24 and release the latchconnection between the lower sash and the operating rods. The lower sashmay then be closed without efi'ecting the position of the operating rods17.

To close the upper sashes it is only necessary to open the lower sash toa position where the latch bolts 21 will engage the latch bolt keepers22 and reconnect the lower sash to the operating rods 17. Closing of thelower sash will then, of course, be accompanied b upward movement of theoperating rods and consequently of the upper sashes.

By making the connectors 18 adjustable on the rods 17 is importantbecause it enables a perfect adjustment to be obtained between thesashes so that they will all close tightly. To further assist in this aspreviously pointed out the latch supports 20 are also adjustable on therods 17. Due to these adjustments I am enabled to fit my apparatus toawning type windows and so connect the sashes that they will all closetightly.

From the foregoing it is obvious that I have provided a simple andcomparatively inexpensive mechanism which may be applied to awning typewindows so that the sashes of the window will operate in unison. Also,my apparatus enables operating of some of the sashes independently ofthe others.

While I have shown the preferred form of my invention, it is to beunderstood that various changes may be made in its construction by thoseskilled in the art without departing from the spirit of the invention asdefined in the a pended claims.

Having thus escribed my invention, what .1! claim and desire to secureby Letters Patent is:

1. In combination with an awning type window including a plurality ofswinging sashes, an operating rod arranged vertically of the sashes atthe interior of the window, connections between the upper sashes andsaid rod, a latch connection between the lower sash and the rod wherebyoperation of the lower sash will normally operate all of the sashes, thereleasing of said latch connection enabling operation of the lower sashindependently of the upper ones.

2. In combination with an awning type window including a plurality ofsashes adapted to swing in a vertical plane, brackets at the interiorside of said sashes, an operating .rod, adjustable connectors fixed onthe opnector reciprocably mounted on the rod and pivoted to the bracketof the lower sash, and operative latch means for latching said slidingconnector to the rod.

3. In combination with an awning type window including a plurality ofsashes adapted to swing in a vertical plane, an operatm rod'at each sideof the window, a pair 0 brackets on each sash positioned one at eachside thereof, connectors on the rods pivotally connecting the same tothe brackets of the upper sashes, a pair of sliding connectorsreciprocably mounted one on each rod and pivotall connected to thebrackets of the lower sas latch means for latching each slidingconnector to the rod upon which it is mounted, and a connection betweenthe latch means of each rod enabling both latch means to besimultaneously released.

4. In combination with an awning type window including a plurality ofsashes adapted to swing in a vertical plane, a bracket fixed to eachsash, a bar carried by said brackets and pivotally connected to eachbracket whereby movement of said bar will swing all of said sashes inunison, and latch means for releasing the engagement between one of saidsashes and said bar whereby said sash may be swung independently of theother sashes.

5. In combination with a window frame and a plurality of sashespivotally mounted therein means connecting the sashes to cause them allto pivot when one is pivoted,

and means for releasing the connection of one sash whereby it may bepivoted independently, all of said means being supported by the sashesand independent of the frame.
